The Granites, Mt Solitaire, Highland Rocks, Mt Theo, NT, 1993 (P599), radiometric line data, AWAGS levelled

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. This The Granites, Mt Solitaire, Highland Rocks, Mt Theo, NT, 1993 (P599), radiometric line data, AWAGS levelled were acquired in 1993 by the NT Government, and consisted of 108984 line-kilometres of data at 500m line spacing and 90m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

放射测量法（或称伽马能谱法）用于检测地球表面附近的伽马射线自然变化，此类伽马射线源自钾（K）、铀（U）与钍（Th）的自然放射性衰变。采集所得数据将通过标准流程开展处理，以确保记录的响应仅由地下岩石产生。处理后得到的数据集可通过解译揭示地下地质构造。经处理的数据将由GA地球物理学家开展质量核验，以确保GA发布的最终数据符合使用需求。1993年北领地（NT）格兰尼特斯山、索利泰山、高地岩石区与西奥山区域的放射测量测线数据（经AWAGS平差，编号P599），由北领地政府于1993年采集，总测线长度达108984测线公里，测线间距为500米，地形离地高度为90米。为约束数据中的长波长分量，研究人员采用独立数据集——全澳航空地球物理调查（Australia-wide Airborne Geophysical Survey, AWAGS）的航空磁测数据，对本次调查数据的基准面进行控制。本调查数据实质上已完成AWAGS基准面平差。
